+* Thermal Sensor (THS) on Allwinner sun8i A23/33 SoCs
+
+Required properties:
+- compatible : should be "allwinner,sun8i-<name>-ths"
+   "allwinner,sun8i-a23-ths": found on A23 SoCs
+   "allwinner,sun8i-a33-ths": found on A33 SoCs
+- reg : physical base address of the controller and length of memory mapped
+	region.
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Shall be "pll2", since the THS on A23/33 is using audio PLL (PLL2).
+- #thermal-sensor-cells : Should be 0. See ./thermal.txt for a description.
+
+Example:
+ths: ths at 01c25000 {
+	#thermal-sensor-cells = <0>;
+	compatible = "allwinner,sun8i-a23-ths";
+	reg = <0x01c25000 0x44>;
+	clocks = <&pll2 0>;
+	clock-names = "pll2";
+};
